I'll throw in something to emphasize a major difference between indexing 
and slicing.

 >>> x = 'Craig Daniel Sirna'
 >>> x[100]
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
IndexError: string index out of range
 >>> x[100:]
''
 >>> x[:100]
'Craig Daniel Sirna'

Inefficient I don't know about, and mostly don't care about either, but 
certainly not the cleanest way to code, at least IMHO.
